In use the bracket 16, may be lowered in the manner described, the end of the shaft 17, strikes upon the base or ground, and the other parts descend from it, so that the roller spacing carrier 12, is at a higher level than the parts 11, 13 and 15, and all of these parts are clear of the grinder 1. A roller spacing carrier filled with roller blanks may be made to replace the carrier containing the finished rolls if one had previously been used in the machine. The spindle 17, is raised rapidly, if desired, by the handle 27, and then the more gradual feeding may be effected by turning the hand wheel 32. Inasmuch as the spindles 3 and 17, are eccentric the path of the grinder is substantially as illustrated by dotted lines in Fig. 3, and inasmuch as the spindle 3, is not vertical but is inclined, the grinder op crates on the rollers to one side of the center and theoretically may be said to operate upon only one roller at a time. This is indicated at the righthand side in Figs. 2 and 3. The roller spacing carrier of course slowly revolves so that the rollers which it carries are ground in succession. The described action tends to push the rollers outwa d where they are being ground but such tendency to outward movement is opposed by the guide 14, upon which the end, the larger end, of each roller abuts as it is being ground. grinding the position of the rolleris referred to its larger end and in a taper roller hearing this same th ng occurs. During the grinding operation suitable lubricating or cooling liquid may run through the connections 9 and 10, and at the completion of the operation the bracket 16, is again lowered and the described procedure repeated. It will be understood that when the roller spacing carrier 12, is handled the rollers or roller blanks are carried by it.

, 34, are pockets in the carrier of the grinder and weigl'it, as shot, may be added to or taken from them to balance the grinder which rotates at a high speed. Inasmuch as the face of the grinder not horizontal but is inclined, it follows that the race 11, must hold the rollers in such position that their conical surfaces are at the same inclination,

The result of this is that in in certain planes of which, as shown, the

inner one 13 higher than the outer one, whereas the face of the grinder is in a plane in parallel with but inclined in respect to the first mentioned planes.

It will be obvious that modifications may be made and I therefore do not desire to limit my invention to the precise arrangement shown and described, but

Having thus explained my invention what I desire to secure by Letters Patent and claim is:

1. A grinder for taper rollers comprising the combination of an annular race having a roller-end thrust guide and in which taper rollers may revolve with portions of their conical surfaces exposed, a grinder having its face parallel with the exposed conical surface of a. roller at one point in the race and inclined in respect to the race, and means for revolving the grinder in eccentric relation to the race, substantially as described.

2. A grinder for taper rollers comprising the combination of a race having a, roller end thrust guide and in which rollers may roll with portions of their conical surfaces exposed, a grinder having its working face parallel with the exposed conical surface of a roller at one point in the race, and means for revolving the grinder across the exposed surface of successive rollers, substantially as described.

3. A grinder for taper rollers comprising the combination of an annular race having a peripheral guide-ring and in which taper rollers may revolve with portions of their conical surfaces exposed, a roller-spacingcarrier concentric with the race, a grinder having its face parallel with the exposed surface of a roller at one point in the race, and means for revolving the grinder and carrier in eccentric relation, substantially as described.
